Same features as the 15TH model with the three lenses provided, one of which is FullRevo monochrome. But this version also includes an RX optical insert already housed inside the glasses. This optical insert, suitable for myopic and astigmatic people, is made of Grilamid TR90 material, therefore non-deformable and practically indestructible. You will only have to take the glasses to your trusted optician who will fit you with corrective lenses. Also very important is the fact that in this version an extra underlying contour (called "rim") of a different color than that already mounted on the glasses themselves is inserted inside the package. Additional temples can be purchased separately to change the look of the glasses. This version is suitable for nearsighted or astigmatic cyclists.
